APPARATUS FOR CLEANING THE CYLINDERS 0F CARDING-MACHINES.

SPECIFICATION forming part of. Letters Patent No. 240,631, dated April26, 1881.

Application filed August 2, 1880. (No model.)

To all whom "it may concern:

Be it known that I, JOHN ABBOTT, a citi zen ofthe United States,residing in Philadelphia, Pennsylvania, have invented certain IImprovements in Apparatus for Cleaning the Cylinders ofCaroling-Machines, of which the following is a specification.

The objectof my invention is to provide a portable apparatus whereby thecleaning of the cylinder-teeth maybe effected more conve'niently andrapidly than" by the use of the usual hand-comb. 1

In the accompanying drawings, Figure 1,, Sheet 1, is a side view of myimproved device for cleaning the teeth of card-cylinders, the: partsbeing in the position to which they are j adjusted when thedevice is notat work; Fig. 2 2, a longitudinal section of a top-flat cardingmachinein connection with which the device l shown in Fig. 1 is intended to beused; Fig. j 3, a longitudinal section, showing the cleaning deviceadjusted for cleaning the cylinder of the carding-machine; Fig. 4, asectional view of part of Fig. 1, with some of the parts in a differentposition from that shown in said figure; j Fig. 5, Sheet 2, a plan viewof parts of Fig. 3; and .Fig. 6, a detached view, drawn tozan enlargedscale, of part of the device.

In Figs. 2 and 3, A represents themain cylindex of a carding-machine; a,the top-flats which act in conjunction therewith; b, the licker-in, andb the doffer.

B, Figs. 1 and 3, is a box or receptacle mounted upon suitable casters,7), and having at "the top projecting arms at d, to which are pivotedarms 0 e, the outer ends of the latter 1 having bearings for the shaftof a brush, D, composed of bristles set in a wooden block or cylinder inthe manner adopted in making an ordinary bristle brush. One end of thebrush shaft projects beyond the arm in which the, bearing is formed, andthis projecting end of the shaft is provided With a cog-Wheel, c,

which engages with a pinion, c turning on a 1 stud on the arm, andprovided with a suitable handle or crank, by which its rotation may bedirected. A transverse shaft, f, extends between the arms 0, in the rearof the brush D, and is adapted to bearings in said arms, the shaft beingprovided with a series of teeth, f, and having near each end a pinion,said pinions, under the circumstances described hereinafter, engagingwith segmental racks g on the arms at.

To slots in the opposite sides of the receptacle B are adapted theopposite ends of a transverse bar, It, having teeth 12, the ends of thebar projecting beyond the sides of the receptacle and being connected toguided rods m, which are acted upon by projections n on the arms 6,these projections, when the arms are adjusted to the position shown inFig. 3, tending to thrust the bar It rearward, so that the projecting.ends will engage with and be retained by the notched ends ofspring-catches p, hung to the sides of the receptacle B.

Springs q tend to draw the toothed bar it forward when it is releasedfrom the control of the catches 19.

When the cleaning device is applied to the carding-machine, as shown inFig. 3, it is retained by the engagement of the upturned ends of theprojections s on the frame of the carding-machine, with the hooked endsit of arms 25 pivoted to the sides of the receptacle B, the rear ends ofthese arms being connectspring, t the tendency of which isto elevate therod t and thus depress the hooked ends of the arms t, and prevent themfrom being accidentallydisengaged from the projections s.

In order to effect the cleaning of the teeth of the cylinder A a numberof the top-flats a are removed, the receptacle B moved to the positionshown in Fig. 3, and the arms 6 turned over, so that the brush D willoccupy the opening made by the removal of the flats a, the ends of thebristles projecting between the teeth of the cylinder and almost to thebases of said teeth. The ends of the arms care provided withadjusting-screws m, Fig. 6, which rest on the side frames of thecarding-machine, and by the adjustment of which the extent to which thebristles penetrate the toothed covering of the cylinder A may be readilygoverned. The brush D, being applied to the teeth of the cylinder, asshown, is rotated by the attendant through the medium of the cog-wheel cand pinion c and at the same time the cylinder A is slowly turned, so asto bring new portions of its toothed covering under the action of thebrush. The bristles of the brush D effectually remove the lint, seeds,and dirt from the teeth of the cylinder without offering ed together bya rod, t acted upon by a spiral that resistance to the passage of theteeth which renders the use of a wire brush objectionable, the frictionbetween the bristles and the teeth not being sufficient to prevent thefree rotation of either brush or cylinder, and not being such as to wearorotherwise injure the teeth. The dirt and lint is stripped from thebrush D by the teeth f of the shaft f, said teeth projecting somedistance beneath the surface of the brush, and preferably occupying theangle shown in Fig. 3 in respect to said brush, the teeth being retainedin this position by the contact of pins y on the shaft f with stops 3 onthe arms 6.

When the cleaning of the teeth of the cylinder has been completed thearmse are turned over to the position shown in Fig. 1, and thereceptacle B released from the frame of the carding-machine and moved tothe next machine to be cleaned. As the arms 0 are turned over thepinions f on the shaft f engage with the segmental racks g, and apartial rotation is thereby imparted to said shaft f, so as to clear theteeth f from the brush D and turn them to the position shown in Fig. 4.When the teeth f have reached this position lugs on the arms 6 actuatethe catches p, and thereby release the bar h from the control of saidcatches, the bar being then drawn forward, owing to the action of thesprings q, so that the teeth h will enter the spaces between the teethf, whereby, when the arms 0 are again turned over to apply the brush Dto the cylinder of another machine, the teeth h will remove from theteeth f the lint, seeds, and dirt which the latter teeth have receivedfrom the brush D. As the arms 0 reach the limit of their movement in thedirection of the arrow, Fig. 1, the projections n on said arms act onthe rods m and effect the retraction of the bar h until its ends arecaught and retained by the spring-catches p.

A cleaning device such as that above described can be readily movedabout and applied to one carding-machine after another, the cleaning ofthe teeth of the carding-cylinders being effected more thoroughly andrapidly than with the usual hand-combs, and without the exercise ofskilled labor, a boy or unskilled attendant being competent to effectthe cleaning of the cylinder with my improved device.

The machine has been especially adapted for cleaning the teeth of thecylinders of topfiat carding-machines, as shown and described; but itmay also be used for cleaning the teeth of the cylinders of machinesusing strippers and workers in place of the top-flats.

I claim as my invention- 1. The within-describedcleaning apparatus, inwhich a box or receptacle, B, mounted on wheels or casters, and providedwith means whereby it may be locked to or released from the frame of acarding-machine, is combined with a brush and brush operating gearinghung to the outer ends of arms 0, pivoted at their opposite ends to saidbox or receptacle, whereby the brush may be turned from a position abovethe receptacle to a position in ad- Vance of the same, for acting on theupper portion of the card-cylinder, as set forth.

2. The combination of the carding-machine with a cleaning-brush, D, andaportable frame or receptacle having pivoted arms carrying thebrush-shaft bearings, and provided with adjusting-screws 00, adapted torest on the frame of the carding-machine, as specified.

3. The combination of a portable frame or receptacle, B, acleaning-brush, D, a shaft, f, having teeth f, arms 0, pivoted to theframe or receptacle B, and carrying the brush D and shaft f, and means,substantially as described, 7

whereby, on the movement of the arms 6, the shaft f will be partiallyrotated and the teeth f willbe caused toengage with or will bedisengaged from thebrush, as set forth.

4. The combination of a frame or receptacle, B, having pivoted arms 6, abrush, D, and toothed shaft f, carried by said arms, means for suitablyrotating the shaft as the arms are turned on their pivots, and a bar, h,capable of moving longitudinally in the frame or receptacle B, andhaving teeth h, for engaging with and cleaning the teeth of the shaft f,as set forth.

5. The combination of the frame or receptacle B, having pivoted arms 6,the brush D, and toothed shaft f, carried by said arms, aspring-actuated bar, It, having teeth h, and means, substantially asdescribed, whereby, on the movement of the arms 6 in one direction, thebar h will be retracted and retained in its retracted position, and onthe movement of the arms in the opposite direction will be released andpermitted to move forward, as set forth. I

6. The combination of a carding-machine having projections s with aportable frame or receptacle, B, carrying a cleaning-brush and providedwith spring-arms t, having hooked ends t, as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
